Clasp and method for assembling the same

Abstract

A clasp including a base connected to at least one end of looping member which has an upper opening at an upper side thereof and which has a front opening at a front side thereof; an arm which is supported by the edge of the base in a rotatable manner, which has a nail portion at a rear end thereof; and which makes up a loop by closing the arm; a push button embedded within the upper opening of the base and communicated with the nail portion of the arm; a first spring which applies a resilient force to the push button in the direction that the push button is projecting outwardly; and a second spring which applies a resilient force to the arm in the direction of opening the arm.

1. A clasp which comprises:
 a base connected to at least one end of looping member, the base having an upper opening at an upper side thereof and which has a front opening at a front side thereof; 
 an arm which is supported by the edge of said base in a rotatable manner, which has a nail portion at a rear end thereof, and which makes up a loop by closing the arm; 
 a push button embedded within the upper opening of the base and communicated with said nail portion of the arm; 
 a first spring which applies a resilient force to said push button in the direction that the push button is projecting outwardly; and 
 a second spring which applies a resilient force to said arm in the direction of opening the arm. 
 
   
   
     2. The clasp according to  claim 1 , wherein a cavity is provided on an inner surface of the base at a portion overlooking from the front opening. 
   
   
     3. The clasp according to  claim 1 , wherein said first spring comprises a coil spring and said second spring is a torsion spring. 
   
   
     4. The clasp according to  claim 1 , wherein said push button has an upper opening provided at an upper side thereof, a back side opening provided at the back side thereof, and a step provided at a front side thereof, and one side of the upper opening is making up a communicating portion. 
   
   
     5. The clasp according to  claim 4 , which is assembled by
 (a) a step for inserting the first spring into the push button from the back side opening thereof; 
 (b) a step for inserting the push button having the first spring inserted therein into the base from the upper opening thereof allowing one end of the first spring for falling into the cavity of the base to thereby cover the front side opening of the base with the push button in the state of applying the resilient force of the first spring to the front opening; and 
 (c) a step for inserting a pin which is connected to the edge of the base into one end of the arm via the second spring to support the arm by the base in a rotable manner. 
 
   
   
     6. An accessory having the clasp according to  claim 1 . 
   
   
     7. The accessory according to  claim 6 , which is necklace, bracelet, anklet, or pendant.
